The equation for the circle below is x ^2 + y^2 = 100. what is the length of the circles radius?
Ganezh [65]

Answer: 10 units.

Step-by-step explanation:

The equation of the circle in Center-radius form is:

(x - h)^2 + (y - k)^2 = r^2

Where the center is (h,k) and "r" is the radius.

The equation of the circle given is:

x ^2 + y^2 = 100

You can observe that is written in Center-radius form.

Then, you can identify that:

r^2=100

Knowing this, you need to solve for "r" to find the lenght of the radius.

This is:

r=\sqrt{100}\\\\r=10

Therefore, the lenght of the radius is 10 units.

densk [106]

Answer:

Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.

Step-by-step explanation:

From. The plot given :

We could approximate the proportion of females older than 60 as follows _

COUNTRY A :

60 - 69 = 0.105

70 - 79 = 0.065

80 - 89 = 0.038

90+ = 0.01

Total = About 0.218

COUNTRY B :

60 - 69 = 0.14

70 - 79 = 0.11

80 - 89 = 0.07

90+ = 0.02

Total = About 0.34

From the estimated proportion, the proportion of females on country B is more than the proportion in country A.
